چکیده
In the solid form of the title imidazolium-based ionic liquid salt, C(18)H(24)N(4) (2+)·2CF(3)SO(3) (-), the complete cation is generated by a crystallographic inversion centre. The five-membered imidazole ring is approximately perpendicular to the six-membered phenyl-ene ring [dihedral angle = 85.11 (11)°]. In the crystal, the components are linked by C-H⋯O interactions.
